Abstract

Synthesis of 2,3,2,3-tetrahydro-1H,1H-[2,2]biindenyl 2 from the dimerization reaction of indene with lithium naphthalenide was carried out and we here report its single crystal X-ray structure. Synthesis and characterization of compounds 3-8 have also been carried out successfully. The stability of biindenyl and its stereochemistry at position 2 and 2 was investigated using density functional theory.

Keywords: ab initio calculations, indene dimerization, bisindan, liquid crystals, birch reduction
